Which theme is best and for what

Hello all! I love wordpress. I was wondering what everyone thinks about the themes I am using on my various sites.

Each site has a different theme, I have been tracking how they work and which ones are liked the most. Let me know what you think. I’m still up in the air on the best way to approach this, kinda learned on my own. Doing ok now though.

this is the ctr theme and seems to work ok, is this the best route to take with a site like this?

There u have it, I use the ctr theme on my low traffic sites and cleaner themes on more authority sites but it seems to hurt the ctr but help the seo?
The conspiracy news website gets the most traffic by far. I guess people like to stay updated on world news, conspiracies health and technology. Either way, I would love to increase my ctr and possibly find more tricks for seo using wordpress and themes.
